TKK HSZ-CK Manual Chain Hoist – Heavy Duty Chain Block 1 Ton to 50 Ton
Products Details
The hoist features a high-efficiency spur gear transmission system combined with needle bearings, significantly reducing hand pull force while improving transmission efficiency. This optimized mechanical design ensures smoother lifting operation and minimizes operator fatigue during continuous use.
One of the key advantages of the HSZ-CK series is TKK's exclusive double pawl spring mechanism. Even if one pawl spring becomes damaged, the second spring continues supporting normal braking operation, providing enhanced operational safety and improving the overall durability of the hoist.
Constructed with a heavy-duty impact-resistant steel housing, the hoist effectively protects internal components from external impact while maintaining excellent structural strength for demanding working environments.
The lifting system utilizes TKK Grade 80 manganese alloy steel load chain, manufactured with high tensile strength, excellent wear resistance, and outstanding fatigue performance. Precision-calibrated chain links provide smooth lifting operation, reduced friction, and extended service life.
Each lifting hook is manufactured from precision forged alloy steel and heat treated to provide superior strength, excellent impact resistance, and reliable safety. Heavy-duty safety latches ensure secure load engagement during lifting operations.
Every TKK HSZ-CK Manual Chain Hoist undergoes comprehensive quality inspections before shipment, including:
- Dynamic Load Test
- Brake Performance Test
- Load Chain Tensile Strength Inspection
- Gear Transmission Inspection
- Hook Strength Test
- Final Functional Inspection
Available in lifting capacities from 1 ton to 50 tons, the HSZ-CK series is widely used for machinery installation, equipment maintenance, warehouse handling, construction projects, shipbuilding, mining, and heavy industrial material handling.
Standard lifting height is 3 meters, while customized lifting heights, chain lengths, and special configurations are available according to customer requirements.
